The spread of hybrid cloud architectures has caused an evolution in the networking solutions used to connect everything. These distributed environments quickly become too complex to manage and leave the potential for gaps in security.
Legacy WAN technology (i.e. MPLS and IPSec VPN) connecting users to multiple local area networks has struggled to meet the performance, management and security demands of these modern hybrid cloud architectures. To address these inadequacies, software-defined WANs (SD-WAN) have evolved to focus on the needs of applications – as opposed to the users.
Supporting the creation of application-driven network architectures, SD-WANs are designed to securely connect applications to remote resources, but in ways that specifically serve the needs of the application. Application-based access policies, QoS, and certificate-based authentication of network traffic are just a few of the examples of the application-centric features that this new breed of networking technology enables.
And because many applications are moving to public cloud environments, but still rely on resources in a variety of on-premise locations, these next generation connectivity solutions have incorporated features that enable this migration. Features such as the flexibility to run on any internet connection, easily deploy from the cloud to any remote environment and centralize visibility across all connections from a single pane of glass, enable ease of management while lowering the total cost of ownership.
Application-driven network architectures are not trying to connect all traffic between two points like a typical branch to branch networking solution. Instead it optimized for the security, compliance and support of a specific application. As the distinction between these two types of networking frameworks becomes more understood, the co-existence of these solutions will become more common.
